Ixesha: 2021-05-11 Indawo: 8

Impompo yamagnetic yenziwa ngamacandelo amathathu: impompo, i-magnetic drive kunye nemoto. Icandelo eliphambili le-magnetic drive liqukethe i-Rotor magnetic yangaphandle, i-rotor yangaphakathi yamagnor kunye nomkhono wokuzihlukanisa ongeyena-magnetic. Xa i-motor iqhuba i-Rotor magnetic yangaphandle ukujikeleza, i-magnetic field ingangena kwi-gap yomoya kunye nezinto ezingezizo-magnetic, kwaye iqhube i-rotor magnetic yangaphakathi exhunywe kwi-impeller ukujikeleza ngokulandelanayo, ukuqonda ukuhanjiswa kwamandla, kunye nokuguqula amandla tywina kwitywina elimileyo. Ngenxa yokuba ishaf pump kunye ne-rotor yangaphakathi yemagnethi ivalwe ngokupheleleyo ngumzimba wempompo kunye nomkhono wokuzahlula, ingxaki "yokubaleka, ukukhupha, ukuvuza, kunye nokuvuza" isonjululwe ngokupheleleyo, kunye nokuvuza kwezinto ezinokutsha, eziqhumayo, ezinobungozi kunye eziyingozi kwi ishishini lokucoca kunye neekhemikhali ngesitywina sempompo liyasuswa. Iingozi ezinokubakho zokhuseleko ziqinisekisa impilo yomzimba kunye nengqondo kunye nemveliso ekhuselekileyo yabasebenzi.

1. Ukusebenza komgaqo wepompo yamagnetic
Iibini zemagnethi (n linani elilinganayo) zihlanganisene ngaphakathi nangaphandle kumazibuthe ojikelezayo wamagnetic actuator kulungelelwaniso oluqhelekileyo, ukuze iinxalenye zomazibuthe zenze inkqubo yemagnethi edityanisiweyo. Xa iipali zemagnethi zangaphakathi nezangaphandle zichasene, oko kukuthi, i-engile yokufuduka phakathi kweepali ezimbini zemagnethi Φ = 0, amandla ombane wemagneti yeyona iphantsi ngeli xesha; xa iipali zemagneti zijikeleza kwipali enye, i-enging displacement angle phakathi kweepali ezimbini zemagnethi Φ = 2π / n, amandla ombane wemagneti mandla ngeli xesha. Emva kokususa amandla angaphandle, kuba iipali zemagneti yenkqubo yemagneti iyagxothana, amandla ombane aya kubuyisela umazibuthe kumandla ombane asezantsi. Emva koko iimagnethi zihamba, ziqhuba i-magnetic magnetic ukujikeleza.

2. Iimpawu zesakhiwo
1. Umazibuthe osisigxina
Iimagnethi ezingapheliyo ezenziwe ngezinto ezinqabileyo ezisemhlabeni zemagneti zinobubanzi obusebenzayo beqondo lobushushu (-45-400 ° C), ukunyanzelana okuphezulu, kunye ne-anisotropy elungileyo kwicala le-magnetic field. I-Demagnetization ayizukwenzeka xa iipali ezifanayo zisondele. Ngumthombo olungileyo wemagnethi yomhlaba.
2. Umkhono wokuzahlula wedwa
Xa kusetyenziswa umkhono wensimbi ozahlula wodwa, umkhono ozahlulayo ukwindawo ye-sinusoidal etshintshayo, kwaye i-eddy yangoku inyanzeliswa kwicandelo lomnqamlezo ngokungqinelana nolwalathiso lwamandla ombane kwaye uguqulwe waba bubushushu. Inkcazo ye-eddy yangoku yile: apho uPe-eddy wangoku; K-rhoqo; Isantya esilinganiswe ngempompo; I-torque yokudlulisa i-T-magnetic; Uxinzelelo lwe-F kwi-spacer; Ububanzi obungaphakathi be-D yesithuba; Ukuxhathisa kwezinto; -izinto eziphathekayoUkuqina kwamandla. Xa impompo iyilelwe, u-n no-T banikwa ziimeko zokusebenza. Ukunciphisa i-eddy yangoku inokuqwalaselwa kuphela kwimiba ye-F, D, njalo njalo. Umkhono wokuzahlula wenziwe ngezinto ezingezizo zesinyithi ezinokuxhathisa okuphezulu kunye namandla aphezulu, asebenza kakhulu ekunciphiseni i-eddy yangoku.

3. Ukulawulwa kokuhamba kokuthambisa kokuthambisa
Xa impompo yamagnetic isebenza, isixa esincinci samanzi kufuneka sisetyenziselwe ukuhlamba nokupholisa indawo ye-gap yangaphakathi phakathi kwerotor yangaphakathi yemagnethi kunye nomkhono owahlulayo kunye nesibini sokungqubana kwesilayidi esityibilikayo. Isantya sokuhamba kwesipholisi sihlala si-2% -3% kwinqanaba lokuhamba kwempompo. Indawo yokurhoxisa phakathi kwerotor yangaphakathi yemagnethi kunye nomkhono wokuzahlula uvelisa ubushushu obuphezulu ngenxa yemisinga eddy. Xa i-lubricant yokupholisa ingonelanga okanye umngxunya wokugungxula awugudanga okanye uvalekile, iqondo lobushushu eliphakathi liya kuba phezulu kuneqondo lobushushu elisebenzayo kumazibuthe osisigxina, kwaye i-Rotor yangaphakathi yemagneti iya ngokuthe ngcembe ilahlekelwe ngumazibuthe wayo kwaye i-magnetic drive iya kusilela. Xa indawo iphakathi ingamanzi okanye ulwelo olusekwe emanzini, amaqondo obushushu akhula kwindawo yochaphazeleko anokugcinwa kwi-3-5 ° C; xa iphakathi nendawo yi-hydrocarbon okanye ioyile, ukunyuka kweqondo lobushushu kwindawo engafakwanga kugcinwe kwi-5-8 ° C.

4. Ukuhambisa ngokuhambisa
Izixhobo zeebheringi ezishenxayo zeempompo zemagnethi zifakwe kwigrafite, ezaliswe yipytetrafluoroethylene, iiceramics zobunjineli njalo njalo. Ngenxa yokuba iiceramics zobunjineli zinokumelana nobushushu obuchanekileyo, ukumelana nokubola, kunye nokuxhathisa ukungqubana, iibheringi ezishenxayo zeempompo zemagnethi ubukhulu becala zenziwe ngeeseramiki zobunjineli. Ngenxa yokuba iiceramics zobunjineli zi brittle kakhulu kwaye zine-coefficient encinci yokwanda, ukucocwa kokuthwala akufuneki kube kuncinci kakhulu ukunqanda iingozi ezixhonyiweyo shaft.
Ukusukela ukuthwala okutyibilikayo kwempompo yemagnethi kufakelwe i-medium ethunyelwayo, kufuneka kusetyenziswe izinto ezahlukeneyo ukwenza iibheringi ngokweemeko ezahlukeneyo zosasazo kunye neemeko zokusebenza.

5. Amanyathelo okukhusela
Xa indawo eqhutyiweyo yemagnethi drive isebenza phantsi kokugcwala kakhulu okanye iRotor ibambekile, ezona ndawo ziphambili neziqhutywa yimagnethi drive ziya kuthi ngokuzenzekelayo zikhusele impompo. Ngeli xesha, umazibuthe osisigxina kwi-actuator yemagneti uya kuvelisa ilahleko eddy kunye nelahleko yemagnethi phantsi kwesenzo samasimi atshintshayo ojikelezayo we-rotor esebenzayo, eya kubangela ukuba ubushushu bemagnethi esisigxina bunyuke kwaye i-actuator yemagneti ityibilike kwaye isilele .
Ezintathu, izibonelelo zempompo kazibuthe
Xa kuthelekiswa neempompo ze-centrifugal ezisebenzisa amatywina oomatshini okanye amatywina okupakisha, iimpompo zemagneti zinezi zinto zilandelayo.
1. Ishafu yempompo iyatshintsha ukusuka kwitywina elinamandla liye kwitywina elimileyo elivalekileyo, kuthintelwe ngokupheleleyo ukuvuza okuphakathi.
2. Akukho sidingo sokuthambisa okuzimeleyo kunye namanzi okupholisa, anciphisa ukusetyenziswa kwamandla.
3. Ukusuka ekudibaniseni ukuhanjiswa ukuya kulungelelwaniso lokudonsa, akukho nxu lumano kunye nokuxabana. Inokusetyenziswa kwamandla asezantsi, ukusebenza ngokukuko okuphezulu, kwaye inesiphumo sokunciphisa ukungcangcazela kunye nokushukuma, okunciphisa ifuthe lokungcangcazela kwemoto kwimpompo yemagnethi kunye nefuthe kwimoto xa impompo isenzeka ukungcangcazela kwe-cavitation.
4. Xa ugcwele kakhulu, irotor yangaphakathi neyangaphandle yemagneti iyatyibilika, ekhusela iimoto kunye nempompo.
Isine, amanyathelo okulumkisa ngokusebenza
1. Thintela amasuntswana angangeni
(1) Ukungcola kwe-Ferromagnetic kunye namasuntswana awavumelekanga ukuba angene kwimpompo yamagnetic drive kwaye athwale izibini ezinobundlobongela.
(2) Emva kokuhambisa indawo ekulula ukuyikhazimlisa okanye ukuyitsala, yigungxule ngexesha (ugalele amanzi acocekileyo kwisampu emva kokumisa impompo, kwaye uyikhuphe emva kwemizuzu eyi-1 yokusebenza) ukuqinisekisa ubomi benkonzo yokuthwala .
(3) Xa uhambisa uhlobo olunee-particles eziqinileyo, kufuneka luhluzwe kwindawo yokungena yombhobho wokumpompoza.
2. Thintela ukusetyenziswa kweedemagnethi
(1) Impompo torque yemagnethi ayinakuyilwa incinci kakhulu.
(2) Kufuneka iqhutywe phantsi kweemeko ezichaziweyo zobushushu, kwaye ubushushu obuphakathi abuvumelekanga ngokungqongqo ukuba ungagqithi kumgangatho. Inzwa yeqondo lobushushu lokumelana neplatinam inokufakwa kumphezulu wangaphandle wemikhono yokuzahlula impompo yamagnetic ukubona ukunyuka kobushushu kwindawo yolawulo, ukuze ikwazi ukuvusa okanye icime xa iqondo lobushushu lingaphezulu komda.
3. Thintela ukukhuhlana okomileyo
(1) Idling ayivunyelwe ngokungqongqo.
(2) Akuvunyelwe ngokungqongqo ukukhupha indawo.
(3) Xa ivali yokuphuma ivaliwe, impompo akufuneki iqhubeke ngokuqhubekayo ngaphezulu kwemizuzu emi-2 ukuthintela i-actuator yemagnethi kubushushu nokungaphumeleli.
